Application filed June 30, 1910. Serial No. 569,722.

To all whom it may concern:

Be it known that I, THOMAS a citizen of the United States, residing at Jersey City, county of Hudson, and State of New Jersey, have invented a new and useful Improvement in Machines for Truing Honing-.Vheels, of which the following is a specification.

This invention relates to a machine for truing honing wheels of. the type used in machines employed in finishing thin replaceable razor blades.

The primary object of the invention is the production of a machine ca able of truing honing wheels without dist-ur bing the mount of the wheel and without disconnecting its operating mechanism.

Another object is to provide a machine having a special fixture adapted solely to support and hold a particular type of honing wheel during the truing operation.

With these and other objects not specifically mentioned in view, the invention consists in certain constructions and combinations which will be hereinafter fully described and then specifically set forth in the claims hereunto appended.

In the accompanying form a part of this s which like characters 0 the same parts, Figure G. SHEEHAN,

drawings which ecification and in reference indicate 1 is a plan view in accordance with the invention, and Fig. 2 is a. side elevation of the structure shown in Fig. 1.

In carrying the invention into effect, there is provided a grinding wheel 1 of suitable abrasive material. This wheel is fixed upon one end of a shaft 2 journaled in a bearing 3 carried by a bracket 4 screwed or otherwise fastened upon a table 5 formed at the upper end of a pedestal 6. A pulley 7 is fixed upon the end of the shaft 2 opposite the grinding wheel 1, and this pulley is driven, by means of a belt 8, from any suitable source of motion, such for instance as an overhead line shaft, not shown.

The table 5 is provided with a slideway 9 upon which is slidably mounted a fixture 10. This fixture is adapted solely to support and hold a particular type of honing wheel with its operating mechanism. This particular type of honing wheel includes a stone wheel 11, which is permanently fixed in a holder 12. This holder is provided with a shaft 13 journaled in a bearing 14.- formed in a tilting frame 15 pivoted a The end of the shaft 13 oppo ASSIGNOR '10 DURHAM DUPLEX PORATION OF NEW YORK.
